Tocillwhom t may concern.' Be it knownthatfI, RANsoM COOK, of Shelburne Falls, inthe county of Franklin and StateofMassachusetts, have invented a V new and usefulmachine for facilitating the `manufact-ure of'certain boring `implements l byturning thelipslbr cuts of such implements with greatexpedition and accuracy; andI do hereby declare that the following i is .a full, clear`,and eXact description of the construction and operation of the same,

reference beingfhad to, the annexed draw-` ings, making a part of this specification, in

f In constructing j the machine, (which is independent of theform on which it stands)` I make it entirely `of iron and steel. `The u V wrench, the screw-shaftand some of the bolts of steel; the handles to the wrench "wheel, some of; the `bolts and the band 1 around the chops of wrought iron and all `"theremainingpartsof cast iron.

shaped that one side of them shall fit into the twist of the auger or bit, in order that whentwo ofthem are `pressed together with fthe auger between them, they shall embrace` nearly its entire surfaceas far as they eX p tend on itslength and thus hold it very firmly. c u i The chops or clamps `@have each a recess near the topfin which to secure thecrimping dies.` `:The chops are connected" at their "lower end'sby jointin a mannerwsimilar to the ordinary blacksmiths vice. A strop of iron 'embraces the chops and `is ...connected i" nNsMycooK, or* `sinergiamann` FALLs, Massiionusn'rfrs.

`The crimpingor clamping dies a, are so` with thecamlever @,Hby a bolt which passes N "Specieation of Letters `lafcerit `1\T`o.v"12i,583, dated March 27, 1855.

through the ends of the strop and through the cam-lever at such distance from its end that when brought to a horizontal position it will press the chops most closely together.

The Wrench wheelcZ, is fitted on the end of the screw-shaft in such a manner that `it may be freely turned, toward or from the workman using it, without turning the shaft.

Slots are cut in `the hub of the wheel in which'the wrench is secured. Handles e c, e, e, are inserted in the "periphery of'tiis wheel for the purpose of turning it;

The wrench, Figs. 3 and 4t, and marked in the drawings of the wheel 3, et, where it Lis shown as inserted in the hub, has a h ole in its `middle for the purpose of l receiving the center of the auger, and slots cut on each 4side ofthe hole to receive the lips of the implement. It is inserted in the hub of the wheel with its face, as shown in Fig. 3, toward the crimping dies. The screw-shaft f, isgmoved, by means of the screw, to the right or left as it may be turned; carrying the wrench and wrench wheel along with it. The hand wheel g, is attached firmly to the `screw shaft and used for turning it.

In using this machine, the cam-lever is 'rst raised to nearly a vertical position', thus allowing the clamps to open. An auger or bit, with the pod twisted and lips shaped as `shown in Fig. 7, being heated red hot, is then placed in one of the crimping dies, with the lips projecting beyond the die and toward the wrench. The upper' end of the `cam-lever is then brought quickly down, thus forcing the other crimping-die against `the auger and firmly holding it between the two dies. A. quick turn is then given to the lscrew shaft which brings the wrench in the hub of the wrench wheel,`into an embrace with the end of the auger, the center of which enters the hole in the wrench while the lips pass into the slots on its side. The

its equivalent, with the Wrench and crimping or clamping dies, as herein substantially set forth and for the purpose mentioned.

2. I also claim the shape of the Wrench substantially as described for the purpose 10 of turning the lips of boring implements.
